Description

Die Erfindung betrifft einen Bombierkopf zur Herstellung von Fahrzeugreifen mit einer Bombiertrommel.The invention relates to a crowning head for the production of vehicle tires with a crowning drum.

Bei konventionellen Fahrzeugreifen ist bekannt die Einlage im Reifenwulst um einen Wulstkern herumzuschlagen. Dadurch wird die Einlage bzw. die Karkasslage fest im Reifenwulst verankert. Solche herkömmlichen Fahrzeugreifen werden dadurch hergestellt, dass zunächst die Innenschicht und die Einlagen als breite Materiallagen auf einer Reifenaufbautrommel angeordnet werden. Anschließend wird der Wulstkern auf die Einlage gesetzt und das Einlagenende um den Kern herumgeschlagen.In conventional vehicle tires, the insert in the tire bead is known to beat around a bead core. As a result, the insert or the carcass ply is firmly anchored in the tire bead. Such conventional vehicle tires are produced by first arranging the inner layer and the inserts as wide layers of material on a tire building drum. Then the bead core is placed on the insert and the insert end is wrapped around the core.

Bei der konventionellen Reifenherstellung wird bei einem Verfahrensschritt das Einlagenende von der Reifeninnenseite um den Wulstkern herumgeschlagen. Bei einem zweistufigen Verfahren zur Herstellung von Fahrzeugreifen wird die Reifenkarkasse auf einer separaten Karkasstrommel aufgebaut. Eine solche Karkasstrommel ist in der Regel relativ komplex aufgebaut.In conventional tire manufacturing, in one process step, the insole end is wrapped around the bead core from the inside of the tire. In a two-stage process for manufacturing vehicle tires, the tire carcass is built on a separate carcass drum. Such a carcass drum is usually constructed relatively complex.

Aus der DE 1 247 615 ist eine Vorrichtung zum Aufbauen eines Fahrzeugreifens bekannt, welche eine im Durchmesser veränderbare Aufbautrommel mit seitlich der Trommel angeordneten Blähkörpern sowie auf die Blähkörper einwirkende Schiebeelemente aufweist. Zum Umschlagen der Karkasslage um die Wulstkerne werden die Blähkörper aufgebläht.From the DE 1 247 615 a device for building a vehicle tire is known, which has a variable diameter build-up drum with the side of the drum arranged blowing bodies and on the inflatable body acting sliding elements. To turn over the carcass ply around the bead cores, the inflatable bodies are inflated.

Die aus der DE 1 579 291 bekannte Vorrichtung zum Reifenaufbau umfasst eine Aufbautrommel sowie mehrere miteinander gelenkig verbundene Hebel zum Umschlagen der Karkasslage. Nach dem Umschlagen fährt eine an einem der Hebel angeordnete Wendelfeder an der die Außenseite des Karkasshochschlages entlang, um ein dichtes Anpressen der Karkasslage zu bewirken. Eine weitere Reifenaufbauvorrichtung mit Blähkörpern zum Umschlagen der Karkasslage ist aus der SU 717 851 A1 bekannt.The from the DE 1 579 291 Known device for tire construction comprises a building drum and a plurality of articulated levers for handling the carcass ply. After folding, a coil spring arranged on one of the levers moves along the outside of the carcass bump, in order to effect a tight pressing of the carcass ply. Another tire building device with inflatable bodies for turning over the carcass ply is known from SU 717 851 A1 known.

Bei den herkömmlichen Reifenaufbauverfahren werden auf der Karkasstrommel beide Seitenwände aufgewickelt. Anschließend wird die Reifenkarkasse mit den bereits applizierten Seitenwänden zu der Bombiertrommel verfahren.
Bei dem Reifenaufbau auf der Bombiertrommel kann es zu Problemen bei der Umschlingung von Seitenwand- und Karkasseinlage um den Reifenkern kommen.In the conventional tire building methods, both sidewalls are wound up on the carcass drum. Subsequently, the tire carcass is moved with the already applied side walls to the crowning drum.
In the tire construction on the crowning drum, problems can be encountered in wrapping sidewall and carcass ply around the tire core.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung bereitzustellen, mit dem die Herstellung von Reifen verbessert wird.The invention has for its object to provide a device with which the production of tires is improved.

Gelöst wird die Aufgabe gemäß Anspruch 1 dadurch, dass am vorderen Ende des Balgträgersegmentes im Andrückbereich zum Reifenwulst zwischen dem vorderen Teil des Hebelarmes und der Innenseite des Andrückteiles im Andrückteil ein hochelastischer Bereich in Form einer Materialaussparung angeordnet ist,
wobei das Andrückteil beim Andrückvorgang an den Reifenwulst mit einer hohen Flexibilität in die Materialaussparung gedrückt werden kann. Ein Vorteil der Erfindung ist insbesondere darin zu sehen, dass durch die neue Gestaltung des Balgträgersegmentes die Herstellung von Fahrzeugreifen mit einer Bombiertrommel wesentlich verbessert wird. Das Andrückteil kann sich bei der Schulterbildung des Reifenrohlings auf der Bombiertrommel optimal an den bombierten Reifenrohling anpassen. Das gilt insbesondere für Fahrzeugreifen, die im Bereich des Reifenwulstes oder der Seitenwand eine sogenannte Felgenrippe aufweisen. Die optimale Anpassung des Andrückteiles, welches ebenfalls als Schulterring bezeichnet wird, wird insbesondere durch den hoch elastischen Bereich des Andrückteiles, in Form einer Materialaussparung gewährleistet. Dadurch kann sich das Andrückteil optimal der äußeren Kontur des Reifenwulstes, bzw. der Seitenwand anpassen. Die Materialaussparung im Bereich des Andrückteiles lässt sich außerdem auf einfache Weise umsetzten und mit dem Hebelarm des Balgträgersegmentes kombinieren. Außerdem lässt sich das neuartige Balgträgersegment optimal für die Herstellung von Fahrzeugreifen mit einem Niederquerschnitt einsetzen. Bei dieser Art von Reifen ist es besonders wichtig, dass bei der Schulterbildung der Schulterring weiter unten im Reifenwulst ansetzten kann. Mit dem Balgträgersegment lassen sich außerdem Lufteinschlüsse im Reifenwulst vermeiden.The object is achieved according to claim 1, characterized in that at the front end of the bellows carrier segment in the pressing region to the tire bead between the front part of the lever arm and the inside of the pressing member in the pressing part a highly elastic region is arranged in the form of a material recess,
wherein the pressing member can be pressed during the Andrückvorgang to the tire bead with a high degree of flexibility in the material recess. An advantage of the invention is to be seen in particular in that the production of vehicle tires with a crowning drum is substantially improved by the new design of the bellows carrier segment. The pressing member can optimally adapt to the cambered green tire in the shoulder formation of the green tire on the crowning drum. This applies in particular to vehicle tires which have a so-called rim rib in the region of the tire bead or the side wall. The optimum adaptation of the pressing member, which is also referred to as a shoulder ring, in particular by the highly elastic region of the pressing member, in the form of a material recess guaranteed. As a result, the pressing member can optimally adapt to the outer contour of the tire bead, or the side wall. The material recess in the region of the pressing member can also be implemented in a simple manner and combine with the lever arm of the bellows carrier segment. In addition, the novel bellows carrier segment can be optimally used for the production of vehicle tires with a low cross section. In this type of tire, it is particularly important that the shoulder ring can attach the shoulder ring further down in the tire bead. In addition, the bellows support segment avoids air pockets in the tire bead.
